In Japan, Pepsi introduces a fun new flavour each summer. This year it is Pepsi Shiso! Shiso is also called perilla. It’s a green leaf that is often served with sashimi or is popular with yakitori (skewered chicken topped with plum paste and wrapped in shiso/perilla). This Pepsi doesn’t taste like cola at all, it’s fizzy sweet soda flavoured like shiso. It’s the kind of taste that you are happy to try once. Last summer, the special Pepsi flavour was Blue Hawaii and the year before, Cucumber!!!
